Press 'Again' to repeat the calibration
check (verification) at a low flow rate.
Press 'Again' to repeat the calibration
check (verification) at a high flow rate.
When a calibration check (verification) at
all three flow rates has been completed
press 'Done' to view the calibration check
(verification) report screen.
The calibration error for expiration and
inspiration at each flow rate are
displayed. The calibration error should be
less that 3%. If a greater error is shown,
repeat the procedure ensuring that the
syringe is emptied and filled in a smooth
manner without jerking the handle. If an
error greater than 3% is still shown,
inspect the turbine transducer and clean
if necessary.
